MACHINE FOR DRIVING GLAZIERS POINTS.

SPECIFICATION forming part of Letters Patent No. 403,886, dated May 21,1889. Application filed November 28, 1888- Serial No. 292,078. (Nomodel.)

To all whom it may concern:

Be it known that I, FRANKLIN HOLLAND, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inMachines for Driving Glaziers Points, of which the following is aspecification.

My invention relates to improvements in machines for driving glazierspoints; and the objects of my improvement are to improve the eiiiciencyof the machine, to render it more convenient for use, and to render itsconstruction simple and substantial.

In the accompanying drawings, Figure 1 is a side elevation of my machinewith the parts in their normal position. Fig. 1 is a radial section ofthe pawlcarrying arm, together with a side elevation of the pawl andspring. Fig. 2 is a front elevation of said machine. Fig. 3 is a rearelevation of a portion thereof with some of the parts in verticalsection on line y y of Fig. 1. Fig. -:i is avertical section thereof online 00 cc of Fig. 2, the same being illustrated with theoperating-lever raised and the hammer drawn back. Fig. 5 is a verticalsection of a receptacle provided with three delivery-slots instead ofonly one. Fig. 6 is a front elevation of the lower portion of themachine, showing an alternative construction. Fig. 7 is Fig. 8 is areverse plan view of the hammer. Fig. 9 is a central vertical section ofthe parts shown in Figs. 6 and 7. Fig. 10 is a sectional viewcorresponding with Fig. 4 of the lower part of the machine, showing amodification of the the driverguard and pawl for holding the hammer-headto the rear, and Fig. 11 is alike view of said pawl and adjacent partswhen in their locking position.

A designates the frame of the machine having two feet, of which the foot10 at the rear is preferably formed of wood, and the foot 11 at thefront side is provided with a vertical opening through it, and withsuitable guides for the hammer-block 12 and driver 13. In the preferredform the side edges of the driver 13 are rolled over to form grooves,which, in connection with the side ledges on the foot 11, serve to guidethe hammer block and driver in their longitudinal movement. The

rear end of the hammer-block 12 is provided with a guide-rod, 14, aroundwhich a spiral spring, 15, is arranged to drive the hammerblock forward.This guide-rod is also provided on its upper side with a recess ornotch, 16, one end of which forms an abutting shoulder for engagementwith the rear end of the lever-pawl 17 for holding the hammer-block backin the position illustrated in Fig. 4. This lever-pawl is depressed atits rear end to engage the notch in the guide-rod by means of a spring,18, which is secured to the upper side of the foot 10.

Pivoted upon a horizontal shaft, 19, there is a revolving receptacle, C,having two circular flanges, 20 21, separated from each other on theirconfronting faces by a space which slightly exceeds the thickness of aglazierpoint, and which flanges flare outwardly from each other to formthe body of the receptacle, as shown. The space between the confrontingfaces of the flanges is maintained by the connecting-posts 22 andholding-screws 23, as shown in Fig. 4.

Access is had to the interior of the revolving receptacle by a removablecap, 24, upon the front, the said cap being made to fit the centralopening in the front, and provided with spring-arms 25 for holding it inplace, said arms being represented by broken lines in Fig. 2. Theopening is notched on one side, as shown at 44, Fig. 2, to enable thespring-arm 25 to be inserted in place. Inasmuch as the machine isportable and may sometimes be turned bottom side up, the up per part ofthe slot or space between the flanges 20 and 21 may be closed by ahorseshoe-shaped piece of metal, 26, the lower ends of which are rivetedor otherwise secured to the back side of the chute 27, which chute issecured to the front side of the frame A by means of screws 28. Thecontour of the interior of the chute and the strip of metal which closesthe upper side of the slot in the receptacle is indicated by brokenlines in Fig. 2. In the construction shown this horseshoe-shaped pieceof metal by being fastened to the stationary chute also serves as themeans for holding the receptacle from worktoo ing longitudinally on itsaxis.

The lower part of the chute is but a little wider than one glazierspoint, said points being triangular in shape, as indicated by brokenlines, forming a triangle in Fig. 2, the same representing a side viewof a glaziers point as caught by the spring 29 within the lowersupplying the chute with points for driving in the manner hereinafterdescribed.

B designates a lever pivoted to the frame A, and provided with adownwardly-proj ecting arm, 30, the lower end of which comes in 'frontof the hammer-block 12, as shown in Figs. 1 and 4, whereby an upwardmovement of said lever B will draw the hammer-block backward far enoughto allow it to be locked in its rearward position by the lever-pawl 17,

v as shown in Fig. 4:. On the front end of the leverB there is a shortarm, 31, to which is pivoted a pitman, 32, the upper end of said pitmanbeing pivoted to the pawl-carrying arm 33, which arm rocks on the shaft19, and one end of which arm carries a spring-pressed pawl, 34, thatengages the ratchet-teeth 35 on the back of the receptacle, whereby areciprocating movement of the lever B will impart a like movement tothepawl-carrying arm, and thereby, through the ratchet-teeth andspring-pawl, move the receptacle intermittently.

At the lower end of the chute there is a slide, 36, which closes thesame and is pressed rearwardly to withdraw it by the spring 37, Fig.

4, and is moved forward by thedownwardlyprojecting arm 30 of the leverB, when said lever is returned to its normal position by means of thespring 38, thereby letting the inwardly-projecting arm of the spring 29into the chute, to obstruct the passage of points through the lower endthereof, every time the lever B is raised, and by bearing against thelower end of said spring pushing it outwardly to withdraw said arm whenthe lever B is in its normal position, in which case the. slide I 36closes the end of the chute, said arm act- -in the footpiece 11 andhammer-block 12, separately from the movement of the driver.

ing again to stop all of the points, excepting the one lying directlyupon said slide, so soon as said slide is again withdrawn.

Within the body of the hammer-block 12 there is a spiral spring, 39,coiled around the shank of the driver-guard 40, said guard beingarranged to slide forward and backward This guard is prevented fromsliding forwardly, under the influence of the spring 39, beyond a givenpoint by means of the projection 41 on the upper side of the driver 13,

which engages a slot in the under side of said guard. An adjllStlTlg-SCI'BW, 42, is placed in the front side of the foot 11, for the.purpose of regulating the distance that a point after being drivenshall project from the gag- .mer-block in its rearward position.

ing-face, as, for instance, the inner face of the sash.

The receptacle being supplied with a number of points the machine isoperated by lifting the lever B from the position shown in Fig. 1 intothat illustrated in Fig. 4:- This movement of the lever causes a partialrevolution of the receptacle, so as to change the position of the pointstherein and causesome of them to fall down to the lower end of thechute, where they will be stopped by the inwardly-projectin g arm of thespring 29 in case they fall after the lever is lifted, or if one hasfallen down before it will be stopped by the slide 36. In case a pointis stopped by the slide'36 when the lever is lifted, it will falldownward into the opening in the chute and upon the top of thedriver-guard 40. The inwardly-projecting arm of the spring 29 willprevent more than one point from falling at one time either by comingunder the edge of the lowest point but one within the chute or bybearing upon its fiat face, in either event preventing other points fromfalling. The

driver-guard 40, when the hammer-block is in its most forward position,has its front end stopped by contact with the bar across the front sideof the foot 11, thereby forcing said guard into the hammer-block whilethe driver 13 is allowed to come nearly or quite flush with the frontside of said foot. When the hammer-block is first drawn backwardly, thespring 39 holds the driver-guard 40 in a stationary position until theprojection 41 reaches the limit of its movement in the under side of thedriver-guard, after which said guard,

driver, and hammer-block move rearwardly together, and the point whichlies upon the top of the driver-guard drops through the opening in thefoot ll and lies upon the face of the glass.

In using the machine the feet 10 and 11 rest upon the glass being set,and the adjustingscrew 42 is pressed firmly against the face of the sashinto which the points are to be driven. Then the hammer-block 12 and itsconnected parts have been drawn backwardly into the position shown inFig. 4, the lever-pawl 17 engages the guide-rod 14 and holds the ham-Upward pressure onthe lever B is then released, and the spring 38 throwsit into its normal position, when the arm 30 strikes the slide 36,thereby olosin g the lower end of the chute and pushing the spring 29forward to withdraw'its arm and let another point fall upon said slide.N

The end of lever B also engages the long end of lever-pawl 17, therebyreleasing the hammer-block,which, under the force of the spring 15,moves forward with a rapid stroke. In

the foot 11 when the under side of the foot at said front serves'to holdthe point down, the driver-guard yielding as the driver 13 continues onto or nearly to the front edge of the foot, as shown in Fig. 1. Thedistance that the adjusting-screw 42 projects beyond the front of thedriver when in this position regulates the length of projection of thebase of the driven point. By turning this screw out or in, thisprojection can be regulated from almost nothing up to any desiredextent.

In the alternative form (shown in Figs. (3 to 9, inclusive) the groovesfor guiding the hammer-block are formed in the foot 11, instead of inthe edge of the driver; but this differ- V ence alone is not asubstantial one and not the main difference between this alternativedevice and that first described. The principal difference resides in thefact that the driver and driver-guard have a fixed relation to eachother, instead of having separate movements, and therefore the drivercannot well be made to come soclosely to the front of the machine. Thedriver-guard 43 is formed integral with the hammer-block 12 and moveswith the driver at all times. Its under side, back of its front end,may, however, be slightly recessed or cut away, so that the driver 13,which is of spring sheet metal, may yield a little under anyirregularities in the surface of the glass. In this construction thefront wall of the opening through the foot 11 extends downwardly only tothe upper face of the driver-guard 43. The operation of this alternativeconstruction will be readily understood from the descriptionhereinbefore given in first describing the machine. An adjusting screwor screws may also be applied to the front of the foot in thisalternative construction.

Still another modification of the driverguard is shown in Fig. 10, inwhich said driver-guard 49 slides within the hammerhead and foot 11 witha movement separate from that of the driver, as in the constructionfirst described, but it is operated differently. In all of theconstructions shown the driver 13 is rigidly secured to and moves withthe hammer-head 12. In Fig. 10 the arm 30 of the lever B is long enoughto enter a slot, 48, in the driver-guard 49 and move said guard in bothdirections. This slot may be long enough, so that the drivei guard mayremain stationary during the first part of the stroke of the arm 30, butshould always be so short that when the arm 30 reaches the rear limit ofits stroke the front end of the guard will be back as far as the rearwall of the opening through the foot 11. If the driverguard moves backfarther than this it will do no harm. As soon as pressure on the lever Bis released and the arm 30 is thrown forward it engages the front wallof the slot 48 in the driver-guard and carries it forward into theposition shown in Fig. 10, the hammer-block and driver meanwhile beingheld back by their retaining-pawl until said pawl is released by theendof lever B. Thus it will be seen that when the driver makes itsforward stroke the driver-guard and under side of the foot at the frontform a continuous guard over the driver to hold the point down.

If desired, a pawl and dog may be used as an equivalent retaining-pawlin place of the lever-pawl17. Such a pawl and dog is illustrated inFigs. 10 and 11, and it has the advantage of being very easily trippedand of holding surely, while it is also very durable. 45 is the pawl and46 the holding-dog, which is pressed upon by the spring 47. Figure 11shows the pawl locked into engagement with the guide-rod 14, and Fig. 10shows the same parts unlocked by means of the end of lever B strikingthe long arm of the dog the same as it strikes the long arm of the pawl17, first described. In the construction first described theengaging-faces of the notch and pawl 17 were just abrupt enough to havethe pawl stay in in place, while in Figs. 10 and 11 the faces are moreinclined, so that when the dog 46 releases the pawl 45 it will slip upout of the notch 16, under the pressure of the driving-spring 15.

The revolving receptacle formed with a slot or open space at theperiphery between two circular flanges which flare outwardly away fromeach other not only performs the function of delivering the points in anedgewise direction into the chute, but by being so formed as to directthe points through the narrow peripheral slot it not only delivers themedgewise, but will retain within it any bent points, or those of anexcessive thickness or imperfection, so that none but flat points of agiven thickness are delivered from said receptacle. It may therefore beused independently of the rest of the machine for assorting the points,and when so used it might be enlarged by the addition of like flanges,so as to increase the number of delivery-slots. An illustration of areceptacle provided with three delivery-slots for this purpose is shownin Fig. 5.
